Essays on Electrical engineering

In isolation applications where one needs to pass signals in presence of transient or continuous high voltages, reject extreme noise, and break ground loops, optical (optocouplers) and magnetic (pulse transformers) coupling isolation are often used. However pulse transformers are much more difficult to design with relative to optocouplers. When dealing with pulse transformers, the load…

Secondarily, its thickness allows for wear over the life of the clutch. However, that wear results from a fundamental drawback of diabetics design. Since the armature is thick and massive, it has a high inertia, and all of its originally stationary mass must be “spun up” to match the rapidly rotating pulley and friction disk…

Photovoltaic cells are solid state devices that convert light directly into electricity. Photovoltaic literally means “light electricity.” These devices can be commonly found providing power for small scale devices such as calculators, watches, and small radios. However, they are not limited to small scale systems. They are also used to power satellites, communications equipment, houses…

The duties of the section involve reagent storage and mixing, determining the dosage of reagents, ample preparation, metallurgical accounting and dispatch of the concentrate for further processing. Production – duties include receiving ore, ore milling, monitoring flotation cells, concentrate handling and tailings handling. The process at the concentrator is semi- automated and is monitored by…

An electric generator is fundamentally an electric motor working backwards. An electric motor converts electrical energy into mechanical energy. and an electric generator converts mechanical energy into electrical energy. An electric generator looks about indistinguishable to an electric motor. Each consists of a cringle that is able to revolve in a magnetic field. The electric…

There is a argument as to whether or non tablets are better than laptops. This is something that truly has interested me. In this essay we will compare the differences between three tablets and three laptops to see if we can find whether tablets are better than laptops or vise versa. Even though tablets are…

Cathode ray tube is used for producing images, when an electron beam hits the surface made out of a phosphorescent, and the cathode ray tube is basically a vacuum tube. An example of a cathode ray tube is a computer desktop and the picture tubes in television are similar to the cathode ray tube in…

Besides connecting the arioso network segments, the backbone may have its own devices that can be accessed by other network segments Metropolitan area network (MAN): MAN spans a city and is Often used to connect remote BANS. MAN in some cases can be considered a citywide BAN and as the geographic distances they cover have…
